What country has the most diverse ways of getting /out/? I have an opportunity to study abroad next fall and I'm trying to narrow down what countries would give me experiences I can't get at my university and surround areas.

I've had my eye of Ireland/Scotland for some time because I think the landscape is quite neat and different from what I am used to. It seems like it would get boring pretty quickly, though. I've been to Germany before and hiked in the Alps and I enjoyed it, but I think I would like to try something else.
